This has already happened. Washing machines, vacuum cleaners, dishwashers, and mass produced food have turned what used to be a full time difficult job into a chore for your spare time. It created more time for people to do paid work. The ironic thing is that nowadays people love some of those chores (like cooking, growing vegetables, or making bread). We should aspire to a society where people have the choice to take pride in what they do.
And to do what they take pride in.
How many people today are really proud of what they do? How many aren't? How many are simply doing it because it pays the bills? Wouldn't it be much better if they didn't have to do that drudgery anymore, and could instead focus on what they really want?
It's not condescending towards the people, it's criticism towards the system. The system is wrong, the people are its victims.
The London riots were not to do with "boredom", but poor race relations between the Metropolitan Police and the black community. The trigger event was http://en.wikipedia.org/wiki/Death_of_Mark_Duggan ; rather similar to the 1992 LA riots, although not on the same scale. Once the race riot had got going and the police lost percieved control of the streets, opportunistic looting started.
That's a strong causal claim you're making there, where's your evidence?
Oh and maybe food and shelter.
I guess one of the topic that will have to be discussed here at some point is the concept of basic income [1]. Its advocates think that it will help such a transition by helping reducing the amount of existing jobs while making sure that everyone can sustain oneself.
